I have a piece with soprano and alto lines (appearing with a brace) and organ.
Music in the alto line is only in the middle of the piece.
I set hiding in layout options and the empty alto line correctly hides on page 1. The middle pages where the alto line has music, correctly show. In the final verse, the alto is tacet until the very end. However, 3 previous systems containing empty alto staves are not hidden.
If I use the hide staves dialogue on the system break of the first empty alto line, it hides not only that system, but also every system until the end, including the final bars which contain music, and past further system breaks.
Am I missing something or is this something which needs sorting?
